I shot in a USPSA match yesterday and one of the guys in my squad, Loke, brought his Segway. He mostly used it to move from stage to stage. But on one stage, after shooting the stage for real, he shot it while riding the Segway. I have my own video but this is better and is already posted on YouTube with this comment by the shooter:

After owning and using a Segway Ninebot for a few months, I got to shoot one of the stages for fun on it. It was a blast. You can see me wanting to go faster but the Segway’s acceleration is pathetic. I’m sure it’s for safety reasons, so I’m ok with that.

Another shooter also had her Segway and was pulling her wagon loaded with her shooting supplies while riding it. It worked surprisingly well even when traversing uneven ground.
